Referring to fig. 4, 5 and 6, a schematic structural diagram of an organic light emitting diode display device according to an embodiment of the disclosure in a second state is shown. In the second state, the left frame L1 and the right frame R1 slide to both sides respectively, so as to drive the display support 200 and the oled display 300 to be stretched outwards. The plane supporting the display support 200 is formed by a left tooth-shaped structure L20 provided above the left housing L1 and a right tooth-shaped structure R20 provided above the right housing R1. The right sliding rail R10 is configured to incline from the upper left to the lower right of the right housing R1, and in the process that the right housing R1 slides rightward, the right sliding rail R10 drives the right sliding block 122 to gradually lift upwards. The left sliding rail L10 is configured to incline from the upper right direction to the lower left direction of the left housing frame L1, and in the process that the left housing frame L1 slides leftwards, the left sliding rail L10 drives the left sliding block 121 to lift upwards.
In one embodiment of the present disclosure, the number of teeth of the left tooth-shaped structure L20 and the right tooth-shaped structure R20 is increased, so that the gaps between the exposed teeth of the left frame L1 and the right frame R1 due to the outward sliding are reduced. In other words, the flatness of the organic light emitting diode display device in the Zhang Zhuang state can be increased by increasing the number of the left and right tooth structures L20 and R20. For example, the number of tooth shapes of the left tooth-shaped structure L20 and the right tooth-shaped structure R20 is greater than 30.
Referring to fig. 7, 8 and 9, a schematic structural diagram of an organic light emitting diode display device according to an embodiment of the disclosure in a third state is shown. In the third state, the left and right frames L1 and R1 slide to the two sides respectively to the end of the left sliding rail L10 where the left sliding block 121 abuts against the end of the right sliding rail R10, compared to the first and second states. In the third state, the right sliding rail R10 is set to incline from the upper left to the lower right of the right housing R1, and the right sliding rail R10 drives the right sliding block 122 to lift up to the limit position against the end of the right sliding rail R10; through the left slide rail L10 that is configured to incline from the upper right direction to the lower left direction of the left housing L1, the left slide rail L10 drives the left slider 121 to lift up to the limit position that abuts against the end of the left slide rail L10. In the third state, the center housing 100 is raised to be flush with the left and right housings L1, R1 to form the same plane, and the display support 200 at the middle portion is supported.
In one embodiment of the present disclosure, a sliding block and chute structure is disposed between the bottoms of the left and right frames L1 and R1 and the central frame 100, so as to limit the left and right frames L1 and R1 to slide in the left and right directions relative to the central frame 100.
In one embodiment of the present disclosure, the bottoms of the left housing frame L1 and the right housing frame R1 are provided with sliding block structures, and two sides of the central housing frame 100, which are close to the left housing frame L1 and the right housing frame R1, are respectively provided with sliding groove structures matched with the sliding block structures.
In one embodiment of the present disclosure, the bottoms of the left housing frame L1 and the right housing frame R1 are provided with a sliding block chute structure formed by mutually staggered tooth-shaped structures, so as to limit the left housing frame L1 and the right housing frame R1 to slide in the left-right direction relative to the central housing frame 100.
However, the display device according to the present disclosure is not limited to 3 display states, and the user can adjust the positions of the left frame L1 and the right frame R1 to change the unfolding degree of the display support 200 and the oled display 300, so as to achieve the effect of changing the volume of the display device and the size of the exposed display screen.
In one embodiment of the present disclosure, the height difference between the highest point and the lowest point of the left sliding rail L10 and the right sliding rail R10 is the same as the height difference between the top surface of the central housing frame 100 and the top surfaces of the left tooth-shaped structure L20 and the right tooth-shaped structure R20, so as to ensure that the top surface of the central housing frame 100 is just raised to be flush with the top surfaces of the left tooth-shaped structure L20 and the right tooth-shaped structure R20 after the Zhang Zuoke frame L1 and the right housing frame R1 are completely supported.
In one embodiment of the present disclosure, the horizontal lengths of the left rail L10 and the right rail R10 are the same as the top surface length of the central frame 100, so as to ensure that the display support 200 and the oled display 300 are exactly 3 times as large as the original ones when the frame L1 and the right frame R1 are fully supported Zhang Zuoke.
In another embodiment of the present disclosure, the horizontal lengths of the left rail L10 and the right rail R10 are different from the top surface of the central housing 100. By arranging the left slide rail L10 and the right slide rail R10 with different horizontal lengths, the sizes of the display support 200 and the OLED display 300 which are unfolded after the complete support Zhang Zuoke frame L1 and the right shell frame R1 are correspondingly changed. For example, when the length of the left rail L10 is half of the central housing 100, the display support 200 and the oled display 300 are approximately 1.5 times larger than the original size when fully supporting the Zhang Zuoke frame L1; when the length of the right rail R10 is half of the central frame 100, the display support 200 and the oled display 300 are approximately 1.5 times larger than the original size when the right frame R1 is fully extended.
In another embodiment of the present disclosure, the horizontal lengths of the left rail L10 and the right rail R10 are different.
Referring to fig. 2 and 5, in a first state in which the left tooth-shaped structure L20 and the right tooth-shaped structure R20 shown in fig. 2 are tightly engaged, the guide rail 130 wraps the guide post M10. In the second state shown in fig. 5, the guide rail 130 covers the guide post M10 but does not cover the guide post M10. However, in one embodiment of the present disclosure, when the left tooth structure L20 is tightly engaged with the right tooth structure R20, the guide rail 130 covers the guide post M10 but does not cover the guide post M10.
In one embodiment of the present disclosure, the display support 200 is a metal plate. The display support 200 is used to increase the flatness of the support surface of the OLED display 300. Further, when the left frame L1 or the right frame R1 slides away from the central frame 100, the display support 200 can significantly reduce the uneven feeling of touching the oled display 300 even if the left tooth-shaped structure L20 and the right tooth-shaped structure R20 are not tightly engaged. In addition, disposing the OLED display 300 on the display support 200 can prevent the OLED display 300 from being pulled directly.
In summary, the disclosure provides an organic light emitting diode display device, which includes a support base, a central housing disposed above the support base, and a left housing slidably connected with the central housing. The upper part of the left shell frame comprises a saw-tooth left tooth type structure. The right shell frame is slidably connected with the central shell frame, and a toothed right tooth structure is arranged above the right shell frame. The display support piece of the left side part is connected with the left shell frame, and the display support piece of the right side part is connected with the right shell frame. The organic light emitting diode display is attached above the display support. When the left frame or the right frame slides to the direction away from the central frame, the left tooth-shaped structure and the right tooth-shaped structure support the expanded part of the display supporting piece, and when the left frame or the right frame slides to the central frame, at least one of the display supporting piece and the organic light emitting diode display on at least one of the left side part and the right side part is curled into the inside of at least one of the left frame and the right frame. By sliding the left and right frames to roll up and stretch the OLED display, the occupied space of the large-sized display is reduced, and the convenience of carrying by a user is increased.
The foregoing is merely a preferred embodiment of the present disclosure, and it should be noted that modifications and adaptations to those skilled in the art may be made without departing from the principles of the present disclosure, which are intended to be comprehended within the scope of the present disclosure.
